Sleeve Auto Bearing Specification Example for Rental Motorcycles: OEM Replacement
Sleeve Auto Bearing Specification Example for Rental Motorcycles: OEM Replacement
This is a worked specification for sleeve auto bearing in a oem replacement programme. It is the document we would send a buyer who asks what exactly they are getting: the material, the dimensions that are actually controlled, the finish, and the checks that happen before anything is packed.
The oem replacement version exists because the duty cycle on rental motorcycles is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually premature wear on the first batch.

- robot welding
- sintering
- shot blasting
- powder coating
Where this example applies
Programmes that run oem replacement most often specify this build for rental motorcycles. Related applications include dealership service, boat trailers, three-wheelers, light trucks, delivery vans.
Checks before packing
- Dimensional report against the approved drawing.
- AQL 1.5 sampling on the finished lot.
- Finish inspection under agreed lighting.
- Carton drop test on the first lot of a new packing specification.
Questions buyers ask
How long does sampling take?
Samples leave the factory in 10 working days, and each revision round adds about 5 days once you have seen the first piece.
Can the specification be held on file?
Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the REACH-compliant build instead of a fresh interpretation.
How is packing specified?
Individual packing, inner box quantity and carton marking are confirmed at quotation stage so the cartons arrive ready for your warehouse.
What testing is included?
Standard lots ship with dimensional and hardness reports. REACH documentation is issued with the shipment when your market requires it.
